Fresh Pond Reservation is a 155-acre kettle-hole reservoir that supplies Cambridge's drinking water, ringed by a paved 2.25-mile perimeter path that draws walkers, runners, and cyclists all day long. Swimming, fishing, and boating in the pond itself are banned to protect the water supply, though a fenced side pond called Little Fresh Pond lets licensed Cambridge dogs swim off-leash.

Common questions

Is Fresh Pond Reservation open today?
Fresh Pond Reservation is a public pond in Cambridge, MA. Posted hours: Dawn to dusk, 365 days a year..
Can I swim at Fresh Pond?
No, the main reservoir is off-limits to swimming, wading, and boating because it is Cambridge's active drinking water supply. The one exception is Little Fresh Pond, a separate side pond where Cambridge-licensed dogs are allowed to swim off-leash; it isn't meant for people.
Can I launch a kayak or canoe here?
Boating of any kind is banned on the reservoir to protect the water supply, and there is no launch, ramp, or dock on the property.
What are the dog rules at Fresh Pond?
Licensed Cambridge dogs can run off-leash if they stay in sight and respond to voice commands, but leashes are required in every parking lot and on several named trails and fields. A handful of spots, including the Ranger Station, Black's Nook, and the Kingsley Nature Playscape, don't allow dogs at all.
Where can I park at Fresh Pond?
Every lot on the property requires a Cambridge resident parking permit year-round, and visitor permits aren't honored. Most visitors without a permit walk in from Alewife station, ride the 72, 74, 75, or 78 bus from Harvard Square, or dock a Bluebike out front.
Are there restrooms at Fresh Pond?
The only public restroom sits inside the Ranger Station building, on the ground floor facing the lake, just off the path near 250 Fresh Pond Parkway.
Can I ice skate on Fresh Pond in winter?
The city doesn't set up or supervise skating here, and the standing ban on swimming and bathing in the reservoir applies whether the surface is liquid or frozen. Skaters should head to one of Cambridge's staffed rinks instead.
